This invention relates to a method of and.

means for treating surfaces, the general object of the inventionbeing to provide means for forming holes in the surface and then filling the holes 5- with suitable material, and when theinvention is being used to form a firm base for highways, landing fields, etc., the material is such as to stabilize the soil in which theholes are formed but when theinvention is used on a lawn or garden the material filling .the holes may be such as to enrich the soil.

For instance, whenthe surface is to be stabilized liquid cement, asphalt and other stabilizing material may be placed in the holes and when the 1 soil is tobe. enriched liquid fertilizer and other enriching'substances may be placed in the holes. Another object of the invention is to provide tamping members which are to be substituted for the hole forming members of the device when it is desired to use the invention to pack the surface. This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim. I

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:--

Figure 1 is a side view of an apparatus constructed in accordance with this invention, and showing it attached to. a tank carrying vehicle.

Figure 2 is a longitudinal sectional view through Figure 1.

Figure 3 is a section on the line 3-3 of Figure l. Figure 4 is a transverse sectional view through one of the rims and showing the projections at the sides thereof.

. Figure 51s a fragmentary side view of said rim. I Figure 6 is an enlarged fragmentary side view of a rim showing the pins pivoted thereto. ,Figure '1 is a sectional view through the gear housing and showing the arrangement'of' gears for transmitting movement from the annular rack.

Figure 8 is a-view in elevation of the intermittent delivery device.

Figure 9 is a similar spray device. v

, Figure 10 is a view'of'a tamplng member, used in-place of the pins when the device is to be used so in packing-a surface.

view of the continuous Figure 11 is a view making a quarter turn from I Figure 10. y

g In these drawings the numeral I indicates a frame which supports the transverse shaft 2 which carries the drum A, said drum being com- 5 posed of a plurality of wheel-like sections which are spaced apart and connected together by the crossbars 4. A plurality of soil penetrating elements or pins 5 is arranged between each pair of the rims of the sections, each pin having a lo rounded head forming an eye and long bolts or rods 6 pass longitudinally through the. drum and said eyes for pivoting the pins to the rims of the sections. Projections 'I- extend from the side faces of the rims of the sections, between thepins 15 so as to limit tilting movementof the pins and as will be seen from Figures 1, 2 and 6 the pins will gradually assume a vertical position as they approach the surface on which the apparatus is traveling so that they will form substantially ver- 2 'tical holes in the surface 3 as shown at b and as the pins are of tapered formation the holes will be tapered.

.When the device is to be used for packing the surface the pins can be removed and the tamping members 8, shown in Figures 10 and 11 substituted therefor. As will be seen these members are so formed'as to tamp or pack the soil as the drum passes over the surface and asmany of these devices 8 can be used as is necessary. 30 I also provide means for filling the holes with material and, if desired, means for placing material on the surface throughwhich the holes pass. The drawings show means for using liquid but it will be understood that ther material can be used Y i when desired.

A rectangular frame C, formed of tubing depends from the supports! at the rear of the frame I and the bottom member of this frame carries the depending nozzles Iii which are spaced 40 the same distance apart as'the holes I) are spaced laterally. A similar frame D depends from the supports 9 and the lower member of this frame carries the depending spray nozzles Ii. A pipe line illeads from the inlets of these two frames C and D, along the frame i to the front thereof where it is connected by a flexible connection i3 with the outlet of a tank ll on a truck frame I! which is connected with the frame i at the front thereof .as shown at ii so that this truck will pull the apparatus over the surface to be operated upon and the truck also carries the liquid which is to be used for treating the surface. A valve 11 is placed in the line l2 and a valve i8 controls the flow of liquid from the line 12 into the frame D. thesevalves being manually The drive between the be of any suitable con- 21 is such that t valve it, which may struction, and the rack will be Brace means I! are 'provided for the members C and D and front and rear legs 3| are provided for the frame I, these legs limiting tilting acn' it is desired to use the spra frame 1) without the frame 0 the connection to the valve I I ing of tubular construction. n

may be placed in the holes formed by the apparatus.

invention will be readily apparent.

It is to be understood that changes may be Having described the invention what is claimed as new is:-

A device of the class frame,'a transverse shaft carried by the frame,

an end 01' the frame, the rectangular frame beogzles depending from the bottom member of the rectangular frame, means for connecting said rectangular frame with a fluid-supply, a valve for controlling the flow of fluid to the rectanlular frame and means including a ring gear on one end of the drum for operating the valve when the nonles are over the holes made by the pins.
